The submarines you want to put under the sea and ice must be complicated. How long have you been making them?

Also, it must be hard to be away from your home for the summer. Can you do exercise on the ship or play sports inside like ping-pong?

Dear Cristof:

Thanks very much for your question. This is the first one we have had from Greece, so we are glad you are following our expedition!

Here are the answers to your questions:

Hanu Singh, the engineer who is part of our team, has been making autonomous underwater vehicles for several years, so he has had lots of experience. However, the two we are using for our Arctic expedition are a different design from his previous ones, and they have been under development for about four years.

It is hard to be away from home during the summer, but we have various ways to exercise. There are seven flights of stairs from the main deck of the ship to the bridge, so that keeps us fit!  (The bridge is the enclosed platform above the main deck of the ship where all the major controls are located.)  We also have an exercise room with a treadmill, rowing machine, bikes and weights, etc., and at the moment, we have a ping-pong tournament going on while we head to our next work site!  After exercising, we can go to the sauna, which is very nice and a good way to relax and get warm after being out on deck!

Hope you will continue to follow along on our adventure!
